Abstract (en)

[origin: WO9838928A1] This invention is an atherectomy device (10) that may reduce the risk of damage to a vessel wall. One rotatable atherectomy burr (152) has a recessed material removal portion lying between less abrasive proximal and distal shoulders (156, 158). The shoulders (156, 158) can have a straight, rounded or elliptical taper. The shoulders (156, 158) perform a cam action when the burr (152) is canted is a vessel, as when passing the burr (152) and guide wire (16) through a tortuous, stenosed vessel path. The shoulders (156, 158) act to align the burr (152) with the path through the vessel, presenting the less abrasive shoulders (156, 158) to the vessel wall while presenting the abrasive portion to a stenosis.
